Specification of Letters Patent.

Patented Feb. 1 1, 1919.

Application led November 16, 1917. 'Serial No. 202,400.

Be it knownthat I, HUQH'K. Brow-nine, a citizen of the UnitedSta-tes,"residing at Richmond, inthe county of Henrico and State of Virginia, haveinvented certain new and useful Improvements in Cement-Brick Machines; and I do hereby declare the tpllowing to be a full, clear, and exact descrip- .tion of the invention, such as will enable others skilled in the art to which it appertains to make and' use the same.

This invention relates to improvements in brick machines of the type forming the subject matter of the Letters Patent anted May 5th, 1914 and numbered 1,095,596, and

has for one of its objects the provision of a novel means of mounting the tampers so that they will n ot become out of alineinent with the mold and thereby obviating the danger of injuring the divisional plates constituting a portion of the mold. l

Another object of this invention. is the provision of novel means of mounting the divisional plates of the molds so that they will be held firmly and be prevented from raising with the tampers and which can be released and sw-ung or partially raised for cleaning thesal'ne when desired. I

A further object of this invention is the provision of means for sliding the division plates rearwardly to expose thebricks after being molded and which means will, when in its initial position eEectively lock the divisional plates in an operative position.

A still further objectof this invention is the provision .of a brick machine of the above stated character, which shall be simple, durable and eiicient, and whichmay be manufactured and sold at a comparatively low cost.- f

With these and otherfobjects in view asY will become more apparent as the descrip.

'tion proceeds, the invention consists in oervention, reference is to be had to the follow-1 ing description and accompanying drawings, in which g l Figure 1 is a side elevation of a brick machine constructed in accordance' with my invention,

Referrlng in detail to the drawings, the numeral 1 indicates a supporting structure which has formed thereon a plurality of legs 2 mounted upon a suitable foundation 3. The legs 2 are reinforced by braces 4. The supporting structure l has formed upon its sides adjacentv its forward end bearings 5 which have ysecured thereto vertical uprights 6. The vertical uprights have their upper endsconnected to bearings 7 which are connected by a. bar 8 carrying a suitable catch 9. The cat/ch 9 is adapted to engage a 'tamper supporting bar 10 which has formed thereon a plurality of tampers 11 arranged in spaced relation to each other as clearly illustrated in Fig. 2. The tamper supporting 'bar 10 has formed upon each end bea-rin'gs 12 which receive rods 13 and are secured thereto by fasteners 14. The rods 13 are oi rectangular formation and are slidably'received by the bearings 5 and 7.. A har 15 connects the lower c'nds `of the rods 18 and has journaled thereto rollers 16. The rollers 16 are adapted to 'be engaged by cams or eccentrics 1 carried by a shait 18 journaled to a pair of the legs 2, whereby upon rotation of the shaft 18 the eccentrics or cams 17 will reciprocate the tampers 11.

A bed plate -19 of skeleton formation is located upon'the supporting structure 1' and hasitsl forward end reduced to receive a pal- -let 20, constituting a bottom wall having end upstanding walls 21 lwhich. are spaced from lio ` of the ,the bed plate when desired.

lateral movement of the divisional platesupon the shaft. A shaft 27 extends through the rear ends ot' the series ot divisional plates except, the end divisional plates which are indicated by the character A and has positioned thereon a plurality oi spacing collars which cooperate with the spacingy collars 26 and preventing' lateral movement of the divisional plates. The end divisional plates A are of a greater height and length than the remaining divisional plates and are slidably received within grooves 2S foi-ined in ribs :'29 carried by the rear longitudinal edges' ot the bed plate, as clearly illustrated in Fie. It will 4be noted that the divisional plates that have the shafts 25 and 27 passing` therethrough may he swung upwardly into an inclined position as illustrated in Fig. 3 when desiring to clean the saine, as the shaft 25 acts as a hinge for the same.

End walls 30 are secured to the ribs 29 and abut the rear Wall 23 and are each provided with an elongated slot 31 to receivel the ends of the shaft 25 which are provided with rollers 32 which engage the walls of the slots 31 so that the divisional plates may be slid rearwardly between the sido walls 30 when desired. The upper edges of the side walls 3 0 are rabbeted as illustrated at 33 to form support-ing shoulders for a hopper 34. The

front wall 37 provided with a plurality or' spaced vertical slots 43 which receivef the front ends of the divisional plates when the -it'roi'it wall is in avertical or closed posii tion. An upper bar 44 is secured to the front wall 37 at its upper edge and has formed thereon a plurality of V-shaped lugs 45 that enter the slots 43 into an engagement with V-shaped notches 46 :torined in the front end of the divisional plates which will hold said divisional plates in a horizontal. position upon the pallet 20 when the front wall sal tion as illustrated in Fig. l, the divisional plates are slid rearwardly upon the bed plate 1.9 to permit the pallet 20 to be removed.

A substantially U-shaped locking member 49 has the ends ol' its arin portions pivoted to the side walls 30 as illustrated at 50,*wliile its web portion is disposed over the front wall 37. The arm portions are provided with notches 52 adjacent their point et forn mation to the Web portion so as to receive the upper edge of the front wall 37. `:Ribs 53 are formed upon the side walls 30'and overlie the pivoted ends of the ariii portions of the U-shaped locking member 49 so as to limit" the downward movement of the saine when the front wall has been swung to an ope-n position which prevents the same from interfering' with the removal of the pallet 20 from the bed plate.

The shaft 18 has secured to one end thereof a pear 54 which meshes with a gear 55 securec to one end of a drive shaft 56. The drive shaft 56 is joiiirnaled. to a pair of the supporting legs 2 and has secured thereon a horizontal shoulders formed by rabhetingl'xed pulley 57 over which a power belt 58 the upper edges of the side .walls 30 are disposed in horizontal alineinent with the upper edges of the end divisional plates A as illustrated in Fig. 4 so that the hopper 34 may bei slid upon the upper edges of the divisional plates A when desired. The hopper 34 has a slidin bottoni wall 35 so that the contents opper may be emptied therefrom when desired. Suitable handles 36 are secured to the hopper and to the sliding; bottom wall 35 for the purpose of actuating the same.

A front wall 37 has secured toits lower edge a bar 39 on which are formed spaced ears 40. The spaced ears 40 are pivoted to spaced ears 41 formed upon the forward ed ge of the bed plate 19. The bar 8f) has formed thereon a plurality of spaced reinforcing' members 42 that extend upwardly against the front wall 37 to reinforce th'e saine. The

travels. An idle pulley 59 is journaled upon the drive shaft 56 adjacent the. fixed pulley 57 tor the purpose ot receivin the power belt 5S when not desiring to diivo er operate the machine.

A belt shiftingA har 60 is slidably mounted upon the supporting struct-ure l and has formed thereon a. pair of spaced fingers 6l that engage upon each edge of the power belt. so that upon sliding-the bar 60, the power holt may be shifted from one pulley to the otliei'. A shaft 62 is journaled to pair of the supporting` legs and has secured' thereto a suit.- ahle t'oot pedal and a rod 63. which rod has its upper cud disposed hetween a pair ot' spaced lugs 64 formed upon the har 60. whereby upon actuating' the toot pedal. the bar 60 may he slid in one direction against the tension ot a spring- (S5 which will slide' Vends and to the side walls 30 as clearly illus' by the influence` of the spring 65 so as to.

stop the operation of the machine when the power belt has been shifted on the idle pulley.

The palle'v 20 is preferably constructed from wood o1 similar material but may be constructed of metal as illustrated in Fig. 11 whiclrclear'ly shows a modified form of pallet in which the bottom wall 67 has its edges turned downwardly to form supporting flanges 68.' The sides 69 have their lower edges disposed at right angles to formattaching flanges 70 which are bolted to thev ends of the bottom' wall 67 providing a construction whereby a number of'pallets, afterl being removed from the machine carrying bricks,'may be piled one upon the otlier`permitting the supporting flanges 68 tocngage the'upper edges of the end walls '69 thereby spacing the bricks in each pallet from the bottom wall of the adjacent pallet. To' reinforce the upright members (i, suitable braces 71 are secured adjacent their upper trated in Fig. 1, thus providing a substan tial rigid construction which will prevent pacting the same therein.

.ln operation, the operating levers 47 are swung to a vertical position movingy the front wall into engagement with the fiieit ends of the divisional plates and are locked' in this position by means of a locking member 49. The hopper containing cement or similar ingredients is then slid forwardly upon the end divisional plates A overlying the other divisional plates which are disposed. over the pallet 20. The slide bottom of the hopper is then withdrawn so as to permit the contents to fall downwardly between the divisional plates. The hopper is then returned to its normal position rest#A ing upon the upper edges of the side walls 30. rlhe tamper bar is then disengaged or released from the catch 9 and simultaneously the operator places his foot upon the foot pedal causing the belt shifting bar 60 to position the power belt upon the fixed pulley 57 which causes the eccentrics or cams Ato ro-f tate and as they rotate they reciprocate the: bars 13 carrying the tampers. The tampers being rcciprocated engage the ingredients or cement between the divisional plates com lll/'hen' the cement has become thoroughly packed between the divisional plates,' the operator releases his foot from the foot pedal and the spring 65 lateral movement of the tampers during their causes the bar G0 to shift the power belt on to the idle pulley 59 and simultaneously the "brake 6G is applied to the fixed pulley stopkping the operation of the machine.

The locking element 49 is then disengaged from the front wall' 37 and the operating levers are swung downwardly moving the front wall with the same and simultaneously sliding the divisional plates rearwardly between the side walls 30, leaving the bricks exposed upon the pallet 20. The pallet 20 is then removed from the machine with the bricks thereon and another pallet substituted in lieu thereof. The operating levers are then again swung to a vertical or closed position and locked by the locking element 49 and the machine is again ready for a second operation.

Vilhile I have shown and described the profe 1redembodiment of my inventiom it will e uhderstood that minor changes in construction, combination and arrangement of/parts may be made without departing fnpm the spirit and scope of the invention as claimed. i
